Molecularly Imprinted Absorbent for Selective Recognition and Binding of Naphthalene

Abstract

Abstract.A novel surface imprinting material was synthesized using a template immobilized on Silica gel matrix by surface imprinting technique using naphthol as template, 3-isocyana to propyltriehthoxysilane as monomer, ethyl silicate as crosslinking agent. FTIR spectrum and scaning electron microscope were adopted for the characterization of the surface and structure of the molecularly imprinted absorbent. The separation and preconcentration characteristics of the imprinted absorbents for naphthalene were researched by batch procedures. The naphthalene molecularly imprinted adsorbent showed high adsorption capacity and significant selectivity for naphthalene.
